Treatment for
Trigger Finger


Cortisone Injection

The first step in the treatment of trigger finger is to halt all activities that may provoke more inflammation and scaring of the affected appendage. The doctor will provide you with a splint that must be worn daily to prevent additional use. The most effective solution would be through Cortisone Injection. A steroid that will successfully shrink inflammation of the tendons. There is a 50% chance that the Cortisone Injection or other anti-inflammatory medication is all you need to correct your case of trigger finger.

Surgery

Depending on the severity of your condition and If trigger finger persists beyond anti-inflammatory medication, surgery may be needed. Trigger finger hand surgery is an outpatient procedure that results in the immediate ability to extend the finger. An incision is made to the palm allowing the surgeon to access the sheath which will be partially cut to accommodate the flexor tendon.

Recovery Time

The recovery time should take no more than a few weeks but swelling and stiffness will most likely take 6 months to fully disappear. A combination of Physical therapy and finger exercises can greatly raise your chances of loosening it up.

Trigger finger is a condition that affects the ability to release or extend the finger smoothly. The finger when given enough force will snap into place similar to pulling a trigger. When fingers contract they use flexor tendons. Flexor tendons attach muscle to bone, when muscles contract the tendons pull the bone as needed. The flexor tendons go through a small tunnel called a tendon sheath. In this case, the trigger finger is experiencing a lock up in the sheath in an attempt to straighten the appendage. The flexor tendon may be irritated or swollen which then makes the process of sliding through the sheath more difficult. The finger or thumb appears to be stuck in a bent position that requires more effort to correct.

Symptoms Associated with Trigger Finger

Symptoms linked to trigger finger are as follows:

What Causes Trigger Finger?

Trigger finger is not in any way associated with the use of firearms but in the manner in which trigger finger behaves. The direct cause for trigger finger is not well known but has a consistency to effect people with diabetes and rheumatoid arthritis. Unlike dupuytren's contracture, it is not linked to any hard manual labor with the hands but more with the sudden change in the tendons characteristics. For reasons not yet known the tendon's cells shape into cells that produce cartilage in the vertebrae. These cells form a knot (nodule) and make sliding through the sheath very difficult.

Sheath is unable to handle swollen tendon creating a snapping effect.

The fluid known as the tenosynovium is responsible for keeping the sheath constantly lubricated to insure flexor tendons slide smoothly. When the sheath narrows, it blocks the tenosynovium in the process causing painful movements through the sheath and at times halting the finger all together into a bent position. If the current circumstance continues, the tendon could develop scaring, escalating the problem. Rheumatoid arthritis, diabetes, hypothyroidism, amyloidosis are a factor of developing trigger finger. Women are much more likely in developing trigger finger then men are.
